Commonalities among these books include the presence of puzzles, exercises, and challenges that aim to improve mental function or knowledge. Additionally, some of the books have a humorous tone and provide interesting facts or myths. However, one book seems to be unrelated to the topic of quizzes and brain function, as it tells a story about a family's struggle in the 1830s.
